Abstract:
Objective To investigate the cerebral regularity of dynamic charge and the correlation with intracranial pressure(ICP),clinical seriousness and prognosis on acute stage of intracerebral hemorrhage(ICH) patients by transcranial Doppler(TCD).Methods 54 patients with first acute supratentorial ICH 24h after onset were studied.All patients were dynamic evaluated by beside TCD on 1st,7th,21st day.The correlation of TCD with ICP,MESSS were studied.Results On the 1st day the TCD abnormity of the acute phase of the ICH occurred mainly in the anterior circulation of cerebrum,in which the cardinal manifestation was high-resistance,low-flow velocity blood waveforms,especially on the bleeding side.Continuous TCD monitoring revealed the low velocity of the cerebral blood flow increased;meanwhile the high value of PI decreased gradually and the TCD monitoring was within the normal range three weeks after the attack.The ICP had negative correlation with the VmMCA,positive correlation with the PI value.MESSS scale had negative correlation with the VmMCA,positive correlation with the PI value.Conclusions The TCD examination can be used to monitor the cerebral hemodynamics of the patients suffering from intracerebral hemorrhage.The combination of fVEP and TCD facilitate the evaluation of the dynamic changes of ICP so as to instruct lowering the ICP.
